Current Products  Turbidity Meters (~$800s - $1000s) Advantages  Cost Less than Spectrometers  Small and Portable Disadvantages  Cannot do color detection on samples  Usually implement detection by use of vials (not real-time analysis) jpg

Current Products  Mass Spectrometers (~$100,000s) Advantages  High resolution detection of a sample’s color content  Very Accurate and Stable System Disadvantages  Not a real-time analysis  Bulky and Not portable  Very High Cost

Current Products  Mini Spectrometers (~$2000s) Advantages  Cost Effective Solution to Mass Spectrometers  Compact Size  Can be implemented to do real- time analysis Disadvantages  Cost More than Turbidity Meters  Lacks some resolution and accuracy to mass spectrometers _large.jpg

Our Product  Advantages: Real-time analysis Small and Portable Cost effective solution to color spectroscopy and turbidity measurements  Disadvantages Probable Low Resolution
